On HP ProBook 4710s (ati hd4330 with fglrx driver) I have a similar problem: - can't control the lcd backlight using gnome-power-manager - can't control the lcd backlight using xbacklight - CAN change the backlight using 'echo -n 0 > /proc/acpi/video/DGFX/LCD/brightness' - when switching to battery the screen gets dimmer - function keys which used to control backlight don't work any more (used to work out of the box on Karmic)
